  • MULTI-MESSAGE MULTI-USER SIGNATURE AGGREGATION
    Publication number: 20220385479
    Abstract: A PQ signature scheme MMSAT that is capable of aggregating and compressing unrelated messages signed individually by different parties. The scheme extends the notion of multi-signatures, which are signatures that support aggregation of signatures on a single message signed by multiple parties.

  • Radiation processing of heavy oils
    Patent number: 8470166
    Abstract: The present invention is drawn to a method of processing heavy paraffinic oils or heavy aromatic oils using radiation chemistry of polyethylene under oxidizing conditions. The process of the invention will result in a chain reaction for oxidative scission as the basis for a radiation processing for heavy paraffinic or aromatic oils. The method of the invention will allow for the cost-efficient and environmentally-friendly processing of heavy oils into lighter petroleum products.

  • Ozone and wear resistance in styrene-butadiene rubber
    Patent number: 4904422
    Abstract: SBR is treated with sulfur, an optional chemical accelerator and a crosslinking agent, under mild heat, to form a preform having sufficient strength to resist handling. The preform is exposed to substantial irradiation on the order of 5-25 Mrad dose of 10 MeV electrons equivalent, which significantly improves wear resistance, tear strength, crack initiation and growth resistance and ozone resistance.

  • Low temperature heat shrinkable polymer material
    Patent number: 4596728
    Abstract: A heat shrinkable polymer material is particularly adapted for implanted biomedical use. A polycrystalline polymer is irradiated to produce crosslinking of its intramolecular structure to thereby impart viscoelasticity. The material is biocompatible and suitable for implanted use, from the standpoints of very low toxicity, ability to retain structural integrity and being non-carcinogenic and, moreover, is heat shrinkable at a temperature compatible with such implanted use.
